* [asan] instrument invoke insns with noreturn attribute (as well as call insns)Kostya Serebryany2013-02-202-5/+27
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175617 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix thumbv5e frame lowering assertion failure.Logan Chien2013-02-202-3/+35
| | | | | | | | | | | | | | | | It is possible that frame pointer is not found in the callee saved info, thus FramePtrSpillFI may be incorrect if we don't check the result of hasFP(MF). Besides, if we enable the stack coloring algorithm, there will be an assertion to ensure the slot is live. But in the test case, %var1 is not live in the prologue of the function, and we will get the assertion failure. Note: There is similar code in ARMFrameLowering.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175616 91177308-0d34-0410-b5e6-96231b3b80d8

* [ms-inline asm] Force the use of a base pointer if the MachineFunction includesChad Rosier2013-02-192-4/+6
| | | | | | | | | | | | | MS-style inline assembly. This is a follow-on to r175334. Forcing a FP to be emitted doesn't ensure it will be used. Therefore, force the base pointer as well. We now treat MS inline assembly in the same way we treat functions with dynamic stack realignment and VLAs. This guarantees the BP will be used to reference parameters and locals. rdar://13218191 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175576 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | excluding visibility bits. Generic STO handling at the Target level. The st_other field of the ELF symbol table is one byte in size. The first 2 bytes are used for generic visibility and are currently handled by llvm. The other six bits are processor specific and need to be set at the target level. A couple of notes: The new static methods for accessing and setting the "other" flags in include/llvm/MC/MCELF.h match the style guide and not the other methods in the file. I don't like the inconsistency, but feel I should follow the prescribed lowerUpper() convention. STO_ value definitions are not specified in gnu land as consistently as the STT_ and STB_ fields. Probably because the latter were defined in a standards doc and the former defined partially in code. I have stuck with the full byte definition of the flags.

Due to the the extract_element, and the bitcast we will uneccessarily generate moves between scalar and vector registers." I added a pattern containing a copy_to_regclass.
